Idaho CAR DMV Practice Test 6

When being approached by an emergency vehicle that is sounding its siren and/or flashing its red or blue lights, you must immediately pull to the nearest curb or edge of the roadway and stop. Remain stopped until the emergency vehicle has passed.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.

If you arrive to an open intersection at the same time as a vehicle to your right, you should yield the right-of-way to that vehicle. You may then proceed when it is safe to do so.

The only method that effectively reduces your BAC is to not drink alcohol for a period of time. Coffee, exercise, and cold showers cannot reduce your BAC or change the effects of alcohol. They can help you remain awake, but they cannot change your BAC or make you sober.

After a minor collision, move your vehicle off the traveled portion of the roadway, if possible. Do not leave the scene of an accident without identifying yourself and rendering assistance.

When changing lanes, you should check your vehicle's blind spots by looking over your shoulder in the direction that you want to move. Always check your mirrors and turn on your directional signal before beginning a lane change.

Upon striking an unattended vehicle, stop and try to locate the owner. If you cannot find the owner, leave a written notice containing your name, your address, and the circumstances of the accident.

Before changing lanes, you should activate your turn signal in the appropriate direction and check your rearview and side mirrors. Look over your shoulder in the direction you plan to move in order to check your blind spot and check the far lane to be sure no one else is trying to enter the same lane as you. Change lanes when you are sure it is safe to do so.

When entering a roadway from a driveway or private road, you must yield the right-of-way to pedestrians and traffic on the roadway.

Pennant-shaped signs usually indicate no passing zones. Text will also be on the sign to confirm that it is a no passing zone.

Under Idaho law, you are considered to be driving under the influence if you are 21 years of age or older and your blood alcohol concentration (BAC) is 0.08 percent or higher. If you are driving and your BAC is lower than 0.08 percent, you may still be convicted of driving under the influence if you have consumed other intoxicating substances.

You should always turn from the lane that is closest to the direction you want to go. Turn into the lane closest to your previous lane.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

If an emergency vehicle with flashing lights is traveling in the area where you are driving, you must make every effort to give them a clear path of travel. If it is safe to do so, pull your vehicle to the side of the road to give the emergency vehicle an open pathway.

If you are involved in a crash, move your vehicle off of the road and stop, if possible. If anyone is injured, call 911 and provide appropriate help. You must report the crash to law enforcement if there is an injury, a death, and/or more than $1,000 in property damage (or more than $200 worth of damage made to non-vehicle government property, such as signs or guardrails).

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

A flashing yellow traffic light at an intersection indicates that drivers must slow down, proceed with caution, and be prepared to stop.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that left turns are prohibited.

Your ability to handle dangerous traffic situations depends largely on searching for and identifying problems before meeting them. Looking far ahead of your vehicle does not mean you should simply stare at the center of the road. You need to continually scan the entire road, including the sides of the road.

This sign indicates that a divided highway begins ahead. The road will split into two one-way roadways separated by a median or divider. You must keep to the right.

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

Yellow lines are used to divide traffic moving in opposite directions.

A steady green light means you may drive through the intersection if the road is clear. You may also turn right or left on a steady green light unless a sign prohibits the turn. When turning, you must yield to other vehicles and pedestrians within the intersection.

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

When you leave your vehicle unattended, you must stop the engine, lock the ignition, remove the key from the ignition, and set the parking brake.

Highway work zones are established according to the type of work underway along the roadway. Signs in work areas are typically diamond-shaped, orange, have black letters or symbols, and serve as a warning that people are working on or near the highway.

Work zones are often stationary, but they may also be present in the form of moving vehicles striping lines, mowing, or removing snow. Work zones are marked by orange signs with black lettering or symbols. Slow down and pay extra attention when approaching or driving through a work zone.

To check your blind spot, glance over your shoulder in the direction that you want to move.

A flashing red light means that you must stop, yield to traffic and pedestrians, and go only when it is safe. At a railroad crossing, a flashing red light indicates that a train is approaching. Yield to the train, and go only when the lights have stopped flashing and all other active warning devices deactivate.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers that the right lane is ending or that the road is narrowing ahead.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

Any defect that may affect the safe operation of a vehicle should be corrected as soon as possible. Defects should be corrected before the vehicle is driven.

This sign indicates that a school crossing is ahead.

Because it is dark, drivers cannot see as well at night as they can during the day. From one half hour after sunset until one half hour before sunrise, or at any other time when persons or vehicles are not visible for 500 feet, drivers must use their headlights.

This sign indicates that right turns are prohibited.

Factors that can affect braking distance include how fast your vehicle is traveling, the condition of your brakes and tires, and the condition of the pavement.

This sign warns that the overpass ahead has a low clearance. Do not proceed if your vehicle is taller than the height indicated (in this case, 13 feet, 6 inches).

Your tires become less effective at clearing water from the road as you increase your speed. If you drive too fast, they may lose their grip entirely, leaving the vehicle sliding on a film of water. This is known as "hydroplaning."

Drowsiness can make people drive so poorly that they appear to be drunk. Opening a window, turning on the radio, or drinking coffee is not enough to make a drowsy driver alert to roadway hazards.
